“…Typical symptoms of GIT involvement are fatigue, generalized weakness, and weight loss [13,14] but may also include constipation, delayed gastric emptying, abdominal distension, intestinal infarction, perforation, malabsorption and GIB [13,15,16]. GIB is observed in 12.5-36% of patients with AL amyloidosis with GIT involvement, although it is rarely the presenting symptom [7,14,[16][17][18]. Our patient presented with multiple GIB events over 3 months, with no known plasma cell dyscrasia and no signs or symptoms of systemic disease.…”

Background: Light chain or AL amyloidosis is a systemic disease that occasionally involves the gastrointestinal tract, but very rarely presents as gastrointestinal bleeding without evidence of systemic involvement. In such cases recognition of amyloidosis as the cause of bleeding is essential in order to rapidly initiate effective treatment to stop the bleeding. Case presentation: We describe a 76-year-old patient who presented with recurrent massive gastrointestinal bleeding as the initial manifestation of AL amyloidosis. One episode necessitated emergency right colectomy, and histopathological analysis of the resected bowel revealed diffuse amyloid infiltration. This finding prompted further investigations, which demonstrated elevated plasma lambda light chain levels, and 10% monoclonal plasma cells in the bone marrow. Treatment with bortezomib, dexamethasone, and daratumumab was initiated and no further gastrointestinal bleeding occurred. Conclusion: The diagnosis of amyloidosis involving the gastrointestinal tract should be considered in adult patients with unexplained recurrent gastrointestinal bleeding.
